Patent CA-2349810-A1 (CA)
Title: Isometric primer extension method and kit for detection and quantification of specific nucleic acid
Inventor: WANG XIAO BING
IPC: C12Q1/68
Filed: 2001-06-07
Abstract: A method for detecting and/or quantifying a target DNA or RNA present in a sample by a isometric primer extension method is disclosed. The method includes carrying out a primer extension reaction in the absence of a free nucleotide so that the primer extension reaction is stopped where the absent nucleotide would have been inserted. Thus, as the amount of incorporation of a labeled nucleotide on the primer extended product is detected, the amount of the target RNA or DNA in the sample is measured.
Patent CA-2351415-A1 (CA)
Title: Cable device for detecting and monitoring rock and soil displacement
Inventor: MATHIS JAMES I
IPC: G01B11/16
Filed: 2000-09-27
Abstract: A cable composed of material capable of conducting light, sound, or electricity is inserted by appropriate means into a material to be examined. A  portion of said cable having predetermined parameters is fixed internally within the material. The cable is equipped with anchors that restrict movement within the material to be examined. Displacement or deformation of the material to be examined results in displacement and deformation of the sensor cable system. The anchors preferably concentrate stress or deformation at specific points of the cable as the cable deforms. The anchors may also allow movement of the cable such that displacement and deformation of the cable within the material is reduced. Monitoring is conducted by attaching an appropriate test instrument to said cable that utilizes time domain reflectometry techniques appropriate to the material composition and characteristics of the cable which may be optical time domain reflectometry (OTDR), electrical time domain reflectometry (TDR) or sound time domain reflectometry (SONAR). Said principles of examination or monitoring of the cable determine location and magnitude of displacement and deformation of the cable within the material to be examined.
Patent CA-2354378-A1 (CA)
Title: Co-factors for trophic factors, and methods of use thereof
Inventor: GAGE FRED HARRISON
IPC: C07K14/81
Filed: 1999-12-13
Abstract: The present invention is based on the discovery and isolation of a co-factor  for trophic factors. It has been discovered that trophic factors require a c o- factor to stimulate and/or potentiate the trophic factor activity and/or specificity. This was clearly identified in low density cells where trophic factors are unable, or at best, at minimal levels, able to proliferate undifferentiated cells without a co-factor. In a particular embodiment of th e present invention, there is provided a composition comprising glycosylated cystatin C (CCg), an FGF co-factor that stimulates proliferation of neural a nd fibroblast associated undifferentiated cells. The N-glycosylation of cystati n C is required for its activity. Moreover, CCg acts in cooperation with basic  fibroblast growth factor (FGF-2) to induce neural progenitor cell proliferation.

Title: Method of making sideframes for railway car trucks
Inventor: BAUER ANTHONY J
IPC: B61F5/52
Filed: 1998-01-05
Abstract: Improvements in cast metal sideframes and bolsters for railway trucks are disclosed, along with improvements in the processes of casting such products and the cores used in the casting process. In one aspect, the cores are consolidated to provide two one-piece end cores, a one-piece center core, and a bottom center core for the sideframe and two one-piece end cores and a center core for the bolster. The consolidated cores may include cores to define various bolt holes. In another aspect, various cores may be made with step joints for an interlocking support without weight-supporting chaplets. In another aspect, a locator boss may be formed on one or more of the cores for proper positioning of the core on the drag mold. Other improvements disclosed include providing a radial draft on the casting surrounding a bolt hole at a core parting or joint line so that nuts and washers may be evenly loaded. In the bolster interior, ribs may be straightened. In another aspect, core prints are used to support the cores on the drag mold surface. The core prints are connected to the core body through necks or bridges that define holes in the cast metal piece. The juncture of the core print and drag mold are spaced from a perimeter of the neck so that any metal fin formed at this juncture is on the exterior of the casting.

IPC: G06F17/30
Filed: 2000-04-13
Abstract: A system integrates a DVD system and a WWW web browser. Universal Resource Locator (URL) information corresponding to sites accessible by the browser are stored in fields within the DVD data. When the user actuates a DVD element that has a corresponding URL, the web browser displays information from that site. When the user actuates an HTML menu or other browser-implemented feature, the DVD system accesses a portion of the DVD data specified in the menu. This arrangement provides for two-way communication, i.e., HTML in the browser is able to control DVD content and vice-versa. Having the WWW information embedded in the DVD brings a number of benefits, the foremost of which is the ability to write a "one size fits all" template web page that can interrogate the DVD for URL information and present WWW content corresponding to the URL synchronized with the DVD information.
